Nah, just messin'... But seriously, if we don't get this thread back on track soon, it might get locked (and that would be of no help to dagguy)!

Fanboy, you must notice. I would pick on you for no reason, I'm not even picking on tim, he's being an ass. Listen to JAY.

ISSON! BOY-EEEE!

Forget it, end the flaming, all of us.

lol you just picked on him

oh yeah, and calling people asses kinda makes you one. anyway, my question was answered in the first several posts so i'll let a mod lock this to prevent futher flaming

Haha, I guess you're right. Let this end the war.

man...no one needs me anymore, i always come in too late to the good questions. Anyway, technically it could be an RF coil (or choke)...just depends on the type of inductor he used

im pretty sure "rf" referrs to 'radio frequency', at least thats the only context i have heard it used in. and it is indeed true that radios (especailly old AM sets) use inductors to tune in to a frequency (in which case, i suppose you would call the inductor an "rf coil"). however, i maintain that the use of the term in this situation is not exactly correct. i do also admit that it might have been slightly nitpickky of me.

haha, i know what RF means, sheesh. But "RF coil" can indeed refer to the grade of inductor he used, it just means that they have a reduced series resistance and lower capacative effects so they can be used at high frequency. If you really want to get picky, you only get into the "RF stuff" when the physical length of your component is greater than about 1/10th of the wavelength (L > wavelength/10). That's when you have to start taking into account transmission line effects, reflections, standing waves and all that good stuff where the regular old voltage and current laws dont apply. I doubt his DC-DC converter has that high a frequency though!

right, so it indeed is not an RF coil.

I used an RF coil in my 5v switching regulator

As far as I know, a number of things about RF coils and inductors are the same.

But that's beside the point, the question has been answered!

If you disagree, I'm afraid I'll have to kidnap your pet chinchilla.

ok...fine, but isnt arguing fun?

Anway, it's good to see that there actually are people that know about electronics on the forum, because most people need help with that sort of stuff.

yeah. im learning a little more every day. like today. and what RF coils are.

interesting. i admit defeat.

and chincillas are really really soft. we had one in our house for a while. those motherf-ers can jump!

there's no defeated as long as you learned something right? You're not defeated, your enlightened...happens to the best of us
